Best Acoustic Diffusers Buyer’s Guide:

(4 Pack) Sound Absorption-Diffuse Acoustic Panel «Wave» for | Red glossy (palstic)

Unlike a home music studio, professional recording studios are built with a great focus on the acoustics of the room. Have you noticed the sound quality in a cathedral or a concert hall is so unique and incredible? This is because these rooms are built while keeping acoustics in mind.

The small rooms in our house lack that quality. Therefore, if you believe that by getting a good condenser microphone or the latest studio monitors you can have a great sound output, unfortunately, you are wrong. Instead of wondering where you are making a mistake or trying new studio equipment to improve the results, you need to work on the acoustic environment of your room.

For this, you need an effective acoustic treatment for your studio.

What is Acoustic Treatment?

An acoustic system controls sound reflections within the room to allow you a quality sound recording experience. A comprehensive acoustic treatment works on three levels requiring different products for each function:

  1. Absorb low frequencies by using Bass Traps.
  2. Absorb mid/high frequencies by using Acoustic Panels.
  3. Scatter the remaining frequencies by using Acoustic Diffusers.

What are the Acoustic Diffusers?

An acoustic diffuser adds ‘diffusion’ into the acoustic setup of your recording studio. They are usually placed on the back wall, or near the tracking area.

The best acoustic diffusers will help with flutters, slap echo, and comb filtering.

To get high-quality sound in your studio room, you need to calculate the size of your room, and then strategically place the acoustic diffusers.

Understanding the Enigma of Diffusion:

To understand why you need the best acoustic diffusers, we need to first understand the concept of diffusion.

Diffusion is the method of scattering the sound energy for getting better sound in space/room.

Sound diffusion and sound absorption are coupled together to create the perfect sound perception in a recording studio. BXI Sound Diffuser - Acoustic Diffusion Panel - Wood - 2 Types - 24'' X 24'' X 2.8'' (2D QRD)

Why is Sound Diffusion Important?

To understand this, let’s take a look at the journey of sound waves in a room. Once the sound is produced, it travels in the room. The walls and ceilings of the room are flat and hard surfaces that reflect integral sound energy.

These reflected waves then travel back and join the original sound waves that are traveling through the air and, are heard by us. And here is when the problem occurs. The strong reflected sound waves combine with the original un-reflected sound waves, and as a result produces reverberation, slap echo, and flutters.

The reflected sound energy is strong and intact, and as a result, produces unwanted noise. This disrupts the hearing experience and affects the sound quality coming from our instruments, and speakers.

The solution is a balanced (50/50) acoustic treatment with sound absorbers, and the best acoustic diffusers. Sound diffusion spreads the reflected energy and retains enough energy in the space to allow us to hear natural sound with optimal quality.

How does an Acoustic Diffuser work?

An acoustic diffuser works a sound diffusor- it maintains the natural sound energy in the room and removes strong echoes simultaneously.

An acoustic diffuser can also create the perception of a large listening room while playing the sound in a small room.

The best acoustic diffusers do more than just scatter sound energy by propagating the waves evenly in directions. It also alters the concentration of waves by distributing the intensity of the initial wave front among different reflections.

Resultantly, the reflected sound energy is now much weaker while our natural sound energy is intact, and can be heard with better quality.

How to choose the best Acoustic Diffusers or Acoustic Diffuser Panels?

Now that you know how an acoustic diffuser can improve the sound quality when listening in your home recording studio, let us now tell you how to choose the best acoustic diffuser panels.

Usually, most home recording studios need 36 to 48 sq. ft. panels of absorbers and diffusers. But this greatly varies from room to room. The number of acoustic diffuser panels you need depends on the size of your room.

Using more than you need may create other acoustic problems like absorbing all mid and high-frequency waves, and making the room sound deadbeat or claustrophobic.

Room Analysis for buying the best Acoustic Diffusers:

Other than the size of the room, other factors may also be considered like the layout of the room and the current acoustics. In short, you need an analysis of your studio room.

What is an acoustic treatment for a recording studio?

Most of the time, when we set up a recording studio in the house, the structure of the room and its surfaces interfere with the sound waves. The reflected sound waves travel back and join the original sound waves. Also, as a result, there might be some disruptions or disturbances in the sound that you hear.

An acoustic treatment uses bass, soundproofing, absorption, and diffusion to improve the sound quality of your recording room.

What do the best acoustics diffusers do?

Acoustic Diffusers scatter the reflected sound waves and weaken them so they have minimal impact on the original sound. As a result, the sound comes with more clarity and tonality.

What is the difference between absorption and diffusion?

Absorption, as the name suggests, is when a microporous surface absorbs the unwanted wavefront.

Diffusion, on the other hand, scatters the sound waves.

The two processes work together to improve the tonality of your recording space.

Are diffusers really necessary?

This depends on your goals.

Most of the time, when building a place like a music studio, concert hall, theatre, or cathedral. Diffuser surfaces are added to the structural designs. So what do you think is just expensive architecture? Is a smartly built acoustic system, that helps in producing great quality sound with tonality and clarity.

However, in a home studio, where you are trying to record anywhere, you don’t have that advantage. The flat and hard surfaces of the room including the floors, walls, and ceilings interfere with and reflect sound waves, and produce unwanted noise.

In such cases, the diffuser is an easy, efficient, and effective solution for targeting sound problems and treating them.
